Geforce mx 4000 not working properly.

I unistall the intergrated 16mb graphics drivers, put in my Geforce mx 4000, run the CD and install the drivers, when i boot the computer back up, my cpu is constantly being used by 100%, And everything is choppy as all get out, if i leave it alone, it will go down, but if i barley move the mouse the CP usage jumps to 70%. Is my processor to crappy to handle this video card?! I just want to know if this card will work at all with my computer. If i uninstall the Integrated graphics Drivers, does that disable it?

Did you go into your bios and change to the agp setting(assuming you card is agp)? If not then this may be the reason for the problem. Youe mobo manual should tell you what settings to use for an agp card.

I checked the BIOS and it is set to PCI.
The white thing with the circle around it, looks like a plug in to connect my card to my mobo, does that need to be connected to work? no such cord came with my card if so.
